Bitcoin Utility Belt

I've made this project to make easy to use a lot of Bitcoin functions that you need to build a website or a NodeJS application. You can read the examples to find out how to use it! Feel free to contribute with code or a donation!

NodeJS Installation

You just need to install the npm package to your project.

npm install bitcoin-utility-belt --save

Here is an example:

// import bitcoin utility belt
let belt = require("bitcoin-utility-belt");
 
// creating random wallets
// type: P2PK (default)
let wallet = belt.wallet.create();
console.log(wallet);

Browser Installation

You just need to import the /dist/bitcoin-utility-belt.js to your HTML to have access to the functions.
Here is an example:

<!-- Importing Bitcoin Utility Belt script -->
<script src="../../dist/bitcoin-utility-belt.min.js"></script>
<script>
  // creating random wallets
  // type: P2PK (default)
  var wallet = belt.wallet.create();
  console.log(wallet);
</script>

How to compile a new browser version

You have already a compiled version in the directory /dist (extended and minified files).
But if you want to compile for your self run the script:

npm run build

Functions

The list below should be very easy to understand. Some of them interact (via HTTPS) with a 3rd Party Blockchain Provider (3PBP). I've made HTML and NodeJS examples, so you can understand how it works!
